Well would you believe it he's gone to slepp on his tum! I put him down and then went to sort toddler, and he started to cry, but only on and off and not a hard cry, more fussing, (I also don't like leaving my toddlers story time) so I left him to it. Just finished stories and checked on him and he's asleep on his front! Not sure what this means for the rest of the night, but he must have relaxed enough to fall asleep!
